What are some potential pitfalls when trying to make dynamically generated links clickable in PHP?

One potential pitfall when trying to make dynamically generated links clickable in PHP is not properly encoding the link to ensure it is valid and safe to use. To solve this, you can use the `urlencode()` function to encode the link before outputting it. 

$url = "http://example.com/page.php?id=1&name=John Doe";
$encodedUrl = urlencode($url);

echo "<a href='$encodedUrl'>Click here</a>";
